Step 1: Shut off gas and power
Shut Off Gas and Power
Main Steps
1. Locate the gas shut-off valve behind the range, typically 1-3 feet from the floor on the wall or floor directly behind the unit. The valve has a lever or knob that aligns with the pipe when open.
2. Turn the gas shut-off valve perpendicular (90 degrees) to the gas pipe. When properly closed, the lever should form a cross or “T” shape with the pipe. You should feel resistance, then a firm stop. Do not force past this stop point.
3. Verify the gas is off by turning on a stovetop burner. Turn the control knob to the “High” position. The burner should not ignite or produce clicking sounds. If it ignites, return to the shut-off valve and ensure it’s fully perpendicular to the pipe.
4. Turn all stovetop burner knobs to the “Off” position.
5. Locate your home’s electrical panel (breaker box). Find the breaker labeled for the kitchen range, typically a 40-amp or 50-amp breaker. The Samsung NX58H5600SS requires a dedicated circuit.
6. Switch the range breaker to the “Off” position. The toggle should move fully to the opposite side with an audible click.
7. Return to the range. Attempt to turn on the oven by pressing the “Bake” button and setting any temperature. The display panel should remain completely dark with no lights, sounds, or display. If the display illuminates, return to the breaker box and verify you switched off the correct breaker.
8. Use a non-contact voltage tester at the outlet behind the range (you’ll access this after pulling the range forward in Step 2). Hold the tester near the outlet prongs. The tester should not beep or light up, confirming no electrical current.
Troubleshooting Tips for This Step
**Gas Valve Won’t Turn**: If the valve is stuck, do not force it with excessive pressure. Apply penetrating oil (WD-40) around the valve stem, wait 5 minutes, then attempt to turn again using both hands. If still stuck, call a licensed plumber or gas technician—a broken valve can cause a gas leak.
**Burner Still Ignites After Closing Valve**: The valve is not fully closed or is defective. Try turning the valve handle an additional quarter-turn. If the burner still ignites, the valve is faulty and must be replaced before proceeding with any repair.
**Can’t Find Correct Breaker**: Turn on the oven to illuminate the display. At the breaker box, flip breakers one at a time until the oven display goes dark. This is your range breaker. Label it clearly for future reference.
**Voltage Tester Shows Power Still Present**: Double-check you turned off the correct breaker. If the breaker is off but voltage remains, there may be two breakers controlling the range (rare but possible). Locate and turn off the second breaker, or shut off the main breaker as a last resort.
**Shared Gas Line**: If your shut-off valve controls multiple appliances (you notice other gas appliances stop working), you’ve closed the main gas line. This is acceptable for this repair, but inform household members that no gas appliances will function during the repair.
Step 2: Remove oven bottom
Remove Oven Bottom
1. Open the oven door fully until it stops at its natural resting position (approximately 90 degrees from closed).
2. Look inside the oven cavity at the bottom surface. You’ll see a flat metal panel (the oven bottom) that covers the burner assembly underneath. This panel is approximately 24 inches wide by 18 inches deep.
3. Locate the two front lift points on the oven bottom panel. These are small rectangular slots or tabs positioned at the front edge of the panel, approximately 6 inches from each side corner.
4. Grip the oven bottom panel at both front lift points with your hands, positioning one hand at each tab location.
5. Lift the front edge of the panel upward approximately 1 inch. The front edge will pivot up while the rear edge stays down.
6. Pull the entire panel forward toward you while maintaining the lifted angle. The rear edge of the panel has two tabs that slide out from slots in the oven cavity’s rear wall.
7. Continue pulling the panel forward and upward until the rear tabs completely clear the slots. The panel will now be free from the oven cavity.
8. Remove the panel completely from the oven and set it aside on a protected surface. The panel may have food debris or residue on it.
9. Look into the now-exposed area beneath where the oven bottom was located. You’ll see the gas burner tube (a long metal tube running left to right), the igniter wire (a thin white or gray wire), and the flame sensor.
10. Check for any loose debris, screws, or small parts that may have fallen into this cavity over time. Remove any debris by hand or with a shop vacuum to prevent interference with the new igniter installation.
11. Verify you can see the igniter clearly. It’s located at the right side of the burner tube, appearing as a white or gray ceramic component approximately 2 inches long with two wire connections.
Troubleshooting Tips for This Step
**If the oven bottom panel won’t lift**: The panel may be stuck due to food residue or grease buildup. Apply firm upward pressure at the front lift points while pulling forward. Rock the panel slightly side-to-side while lifting to break any adhesion.
**If the rear tabs won’t slide out**: You haven’t lifted the front edge high enough. Lift the front edge a full 1-2 inches before pulling forward. The rear tabs must clear the height of the slots before they can slide out horizontally.
**If you see wires attached to the oven bottom panel**: This model does not have wires connected to the oven bottom itself. If you see wires, they run underneath the panel and are not attached to it. Do not pull on these wires.
**If the panel appears warped or damaged**: The panel should still remove using the same method. Warping from heat is normal and won’t prevent removal—apply more lifting force at the front edge to compensate for any distortion.
Step 3: Disconnect igniter wires
Disconnect Igniter Wires
1. Locate the wire connector attached to the oven igniter. You’ll see a white plastic connector block approximately 1 inch wide with two wires coming from it – typically both wires have white insulation.
2. Trace these two white wires from the igniter back 8-10 inches toward the left side of the oven cavity where they connect to a matching white female connector from the main wiring harness.
3. Grasp the white plastic connector housing (not the wires themselves) on both the igniter side and the harness side with your thumb and forefinger.
4. Pull the two connector halves straight apart with firm, steady pressure. The connectors should separate with moderate resistance – apply 5-10 pounds of pulling force. If the connector doesn’t budge, wiggle it side-to-side while pulling to break the connection seal.
5. Once separated, you’ll see two metal blade terminals inside each connector half. The igniter wires are not color-coded for polarity – either wire can connect to either terminal since igniters don’t have polarity requirements.
6. Move the loose harness connector (the one still attached to the range wiring) toward the back left corner of the oven cavity and drape it over the side frame rail to keep it out of your work area.
7. Examine both connector halves for carbon buildup or discoloration. Black or brown deposits on the metal terminals indicate overheating from a failing igniter. Wipe the harness connector terminals clean with a dry cloth.
Troubleshooting: What If Wires Become Disconnected
8. If a wire pulls out of the connector housing during disconnection, note that the igniter wires have no polarity. When reconnecting later, insert either wire into either terminal slot in the connector housing.
9. To reinsert a loose wire into the connector: Push the metal blade terminal straight into the rectangular slot in the back of the white connector housing until you hear and feel a click. The terminal should lock in place.
10. Verify the terminal is secure by pulling gently on the wire – it should require more than 10 pounds of force to remove. If it pulls out easily, the locking tab inside the connector hasn’t engaged.
Common Connection Mistakes to Avoid
– **Never pull on the wires themselves** – always grasp the plastic connector housing. Pulling wires can separate the wire from the terminal inside the connector.
– **Don’t twist the connector while pulling** – this can bend the blade terminals inside, making reconnection difficult.
– **Igniter wires are interchangeable** – unlike other electrical components with red/black/white color coding, these two white igniter wires can connect in either orientation.
Verification Method
11. With the connector separated, inspect the two metal terminals on the igniter side. They should be straight, not bent or corroded. Bent terminals indicate the connector was twisted during a previous removal.
Step 4: Remove mounting screws
Remove Mounting Screws
1. Locate the two mounting screws securing the igniter assembly to the burner tube bracket. These screws are positioned at the top and bottom of the igniter mounting bracket, approximately 1.5 inches apart.
2. Identify the screw type: these are hex head screws requiring a 5/16-inch nut driver or socket wrench. Do not use a Phillips or flathead screwdriver as this will strip the screw heads.
3. Check for wire interference before attempting to access the screws. You’ll see two white wires (the igniter leads) running from the igniter assembly. These wires may drape across the mounting area, blocking clear access to the bottom screw.
4. If wires block the bottom screw, push the wire bundle gently upward toward the oven ceiling by approximately 2 inches. The wires have enough slack to move without tension. Hold them temporarily against the burner tube or tuck them behind the adjacent mounting bracket.
5. Insert your 5/16-inch nut driver onto the top mounting screw. Turn counterclockwise 4-6 full rotations until the screw releases completely from the bracket. The screw is approximately 3/4 inch long.
6. Place the removed screw in a container immediately. These small screws easily fall into the oven cavity and become difficult to retrieve.
7. Support the igniter assembly with your non-dominant hand while removing the second screw. The igniter is now held only by the bottom screw and will drop if unsupported.
8. Insert the nut driver onto the bottom mounting screw. Turn counterclockwise 4-6 full rotations until the screw releases completely.
9. Continue holding the igniter assembly as you extract the bottom screw. Remove the screw fully and place it with the first screw.
10. The igniter assembly is now free from the mounting bracket but still connected by its two white wires. Do not pull or tug on the igniter itself—handle only by the metal mounting bracket attached to the ceramic igniter body.
Troubleshooting Tips for This Step
**If screws won’t turn**: These screws can corrode or seize from heat exposure. Apply 2-3 drops of penetrating oil (like WD-40) around the screw head and wait 5 minutes before attempting removal again. If still stuck, apply firm downward pressure while turning to prevent stripping.
**If a screw falls into the oven cavity**: Use a magnetic pickup tool or flexible claw grabber to retrieve it. Check the area beneath the burner tube and around the gas orifice. Do not operate the oven until the screw is recovered, as it could interfere with gas flow or ignition.
**If the igniter bracket is bent**: The mounting bracket may have warped from heat, causing screws to bind. Apply steady outward pressure on the bracket edge while removing the bottom screw to create clearance.
**If wires pull tight during screw removal**: Stop immediately. The wire routing may be catching on another component. Trace the wires back to their connection point (approximately 8 inches toward the rear wall) and identify what’s restricting movement. Gently reposition any wire clips or ties creating tension before proceeding.
Step 5: Install new igniter
Install New Igniter
1. Remove the new igniter from its packaging and inspect it for the two wire leads extending from the ceramic body – typically white or cream-colored wires with spade connectors at the ends.
2. Position the new igniter into the mounting bracket at the rear of the oven burner chamber, aligning the two screw holes in the metal mounting bracket on the igniter with the holes where you removed the old igniter.
3. Insert the two hex-head screws (5/16-inch) through the mounting bracket holes and hand-thread them into the threaded holes in the burner box. The igniter probe should extend toward the center of the burner opening.
4. Use a 1/4-inch nut driver or socket wrench to tighten both mounting screws in an alternating pattern – turn the left screw 2-3 rotations, then the right screw 2-3 rotations. Continue alternating until both screws are snug but not overtightened. The igniter should sit flat against the burner box surface without gaps.
5. Locate the wire harness connector coming from the oven – this is a two-wire connector with one wire attached to each terminal. The wires are typically both white or one white and one brown/gray.
6. Connect the igniter’s wire leads to the oven wire harness. For this model, polarity does not matter – either igniter wire can connect to either harness wire. Push each spade connector from the igniter wire onto the corresponding male terminal on the harness wire until you feel resistance stop and the connector seats fully.
7. Verify each wire connection by gently pulling on each wire individually with 2-3 pounds of force. The connector should remain firmly attached without sliding off. If a connector pulls off, push it back on with more force until it clicks or seats completely past the retention tab.
8. Position the wire leads along the left side of the burner box, routing them away from the burner ports and the igniter probe. The wires should not cross over the gas flow path or touch any part of the burner tube.
9. Use your hand to push the igniter probe gently to confirm it does not move in the mounting bracket. Any movement indicates loose mounting screws – retighten them an additional quarter turn.
**Troubleshooting for This Step:**
– **If the igniter doesn’t fit the mounting holes:** The wrong igniter model was supplied. Verify the part number matches DG94-00520A for this range model.
– **If wire connectors are too loose and fall off:** The spade connector size is incorrect. The igniter should have female spade connectors that fit snugly on the male terminals. Gently squeeze the female connector opening with needle-nose pliers to tighten it, then reconnect.
– **If you cannot see which wire goes where:** Both igniter wires are interchangeable on this model – there is no positive or negative. Simply connect one igniter wire to one harness terminal and the other igniter wire to the other harness terminal.
– **If mounting screws won’t tighten:** You may be cross-threading. Back out both screws completely, realign the igniter bracket, and restart threading screws by hand before using the nut driver.
